RESEARCH ON SEPARATION AND CONCENTRATION OF LUNAR DERIVED MATERIALS IS PROPOSED BASED ON ADVANCED ENERGY DYNAMICS' STATE OF THE ART EXPERIENCE IN DRY ELECTROSTATIC SEPARATION.THE TECHNICAL FEASIBILITY OF SEPARATING THESE MATERIALS INTO A VARIETY OF CHEMICALLY DISTINCT FRACTIONS USING A NOVEL COUNTERCURRENT ELECTROSTATIC PROCESS WILL BE INVESTIGATED. THE ELECTROSTATIC SEPARATOR TO BE USED IS IDEALL ...

THIS RESEARCH PROJECT WILL DEMONSTRATE THE TECHNICAL AND ECONOMIC FEASIBILITY OF A MAGNETIC SEPARATOR FOR OPERATION ON PULVERIZED COAL. A THEORETICAL COMPARISON OF THE SEPARATOR WITH WORK PUBLISHED ON OPEN GRADIENT MAGNETIC SEPARATION BY THE OAK RIDGE NATIONAL LABORATORY INDICATES THAT THE SEPARATOR WILL HAVE HIGH LEVELS OF ASH CLEANING. THIS IS BECAUSE OF ITS COUNTERCURRENT PRINCIPLE OF OPERATION ...

THE PURPOSE OF THIS PROPOSAL IS TO DESIGN, CONSTRUCT AND TEST A LABORATORY VERSION OF A PASSIVE CHLOROPHYLL FLUORESCENCE SENSOR SUITABLE FOR MONITORING LARGE AREAS OF VEGETATION (> 1 M2). THE LINE DISCRIMINATOR METHOD WE PROPOSE EXPLOITS A COINCIDENCE BETWEEN AN ABSORPTION LINE OFATMOSPHERIC OXYGEN AND THE R1 LINE OF A COOLED RUBY CRYSTAL,BOTH OF WHICH LIE NEAR THE PEAK OF THE CHLOROPHYLL FLUORESC ...

THERE IS A NEED FOR AN INEXPENSIVE, COMPACT, LOW MAINTENANCE SUB-PICOSECOND OPTICAL PULSE SOURCE TO DRIVE AN OPTICALLY SAMPLED AND TRIGGERED OSCILLOSCOPE. ADEQUATE LASER SOURCES PRESENTLY OCCUPY TEN SQUARE FEET AND REQUIRE REGULAR MAINTENANCE, 20 KW OF ELECTRICITY, AND COOLING WATER; AND THEY COMPRISE THE MAIN COST ITEM IN THE PICOSECOND OSCILLOSCOPE. THE NEW PULSED LASER UNDER DEVELOPMENT IN THIS ...

ROBOTICS IS BECOMING AN INCREASINGLY IMPORTANT FIELD IN RESEARCH AND MANUFACTURING. MOST ROBOTS, HOWEVER, EITHER PERFORM REPETITIVE PREPROGRAMMED OPERATIONS OR ARE GUIDED BY A HUMAN OPERATOR. THIS IS NOT PRACTICAL IN MANY APPLICATIONS WHERE AUTONOMOUS OPERATION IS REQUIRED, AND THE MOST IMPORTANT IMPROVEMENTS IN FUTURE GENERATIONS OF ROBOTS, ESPECIALLY FOR SPACE APPLICATIONS, WILL COME IN THE AREA ...

ONE OF THE MOST EXCITING GOALS OF THE NASA SPACE PROGRAM IS TO LAND A VEHICLE ON MARS AND CONDUCT PHYSICAL AND CHEMICAL MEASUREMENTS OF THE MARTIAN SURFACE. OF THE VARIOUS ANALYTICAL TECHNIQUES BEING CONSIDERED FOR THE LANDER MISSION, X-RAY FLUORESCENCE ANALYSIS OFFERS THE POSSIBILITY OF PROVIDING THE IN-SITU INFORMATION ABOUT THE CHEMICAL COMPOSITION OF THE PROSPECTIVE SAMPLES WHICH WILL BE SELEC ...

ONE OF THE MOST ACTIVE AND CHALLENGING FIELDS IN MOLECULAR BIOLOGY TODAY IS THE GENETIC STUDY OF EUKARYOTIC SYSTEMS. THE PRELIMINARY, BUT OFTEN RATE LIMITING, STEPS IN THIS AREA ARE THE DNA TRANSFER/HYBRIDIZATION TECHNOLOGIES ASSOCIATED WITH GENE MAPPING, AND THE SCREENING OF DNA LIBRARIES FOR GENE ISOLATION. THESE PROCEDURES USE RADIOLABELED HYBRIDIZATION TECHNIQUES AND AUTORADIOGRAPHY TO ACHIEVE ...

THE SAFE, RELIABLE, AND EFFICIENT OPERATION OF NUCLEAR POWER PLANTS REQUIRES ADVANCED OPERATOR DECISION AIDS AS WELL AS CONTROL AND PROTECTION SYSTEMS. A PREDICTIVE EXPERT SYSTEM FOR PLANNING POWER MANEUVERS WILL BE INVESTIGATED AS ONE SUCH OPERATOR AID. IN THE PHASE I WORK THE FEASIBILITY OF THE SYSTEM WILL BE DEMONSTRATED VIA A ROBUST NEUTRONICS MODEL, USING THE TRANSIENT FEW-GROUP NEUTRON DIFFU ...

PRESENTLY AVAILABLE MASS SPECTROMETER-BASED VACUUM INSTRUMENTS ARE NOT SUITABLE FOR USE IN ANTICIPATED FUSION FACILITIES, WHERE TRITIUM WILL BE USED. THE ION SOURCE IS THE PRIMARY LIMITATION. THIS R&D PROGRAM WILL LEAD TO DEVELOPMENT OF A MINIATURE ECR (ELECTRON CYCLOTRON RESONANT)MICROWAVE ION SOURCE FOR APPLICATION IN LEAK DETECTORS AND VACUUM INSTRUMENTATION. THE ECR ION SOURCE CAN BE DEVELOPED ...
